chash

The cash being completed I walked to it and examined it's construction. it is in a high plain about 40 yards distant from a steep bluff of the South branch on it's nothern side; the situation a dry one which is always necessary. a place being fixed on for a cash, a circle abut 20 inches in diameter is first discribed, the terf or sod of this circle is carefully removed, being taken out as entire as possible in order that it may be replaced in the same situation when the chash is filled and secured. this circular hole is then sunk perpendicularly to the debth of one foot, if the ground be not firm somewhat deeper. they then begin to work it out wider as they proceed downwards untill they get it about six or seven feet deep giving it nearly the shape of the kettle or lower part of a large still. it's bottom is also somewhat sunk in the center. the dementions of the cash is in proportion to the quantity of articles intended to be deposited. as the earth is dug it is handed up in a vessel and carefully laid on a skin or cloth and then carryed to some place where it can be thrown in such manner as to conseal it usually into some runing stream wher it is washed away and leaves no traces which might lead to the discovery of the cash. before the goods are deposited they must be well dryed; a parsel of small dry sticks are then collected and with them a floor is maid of three or four inches thick which is then covered with some dry hay or a raw hide well dryed; on this the articles are deposited, taking care to keep them from touching the walls by putting other dry sticks between as you stoe away the merchandize, when nearly full the goods are covered with a skin and earth thrown in and well ramed untill with the addition of the turf furst removed the whole is on a level with the serface of the ground. in this manner dryed skins or merchandize will keep perfectly sound for several years. the traders of the Missouri, particularly those engaged in the trade with the Siouxs are obliged to have frequent recourse to this method in order to avoyd being robed. most of the men are busily engaged dressing skins for cloathing.
